-* Create rectangular and polygonal bounding box annotations for objects in images
+* Create rectangular and polygonal ("vertices-clicking" and "freehand-drawing" modes) bounding box annotations for objects in images
 * Export and import  rectangular and polygonal bounding box annotations to and from JSON and XML files (using [Pascal VOC](http://host.robots.ox.ac.uk/pascal/VOC/) format)
 * Export and import rectangular bounding box annotations using the [YOLO](https://pjreddie.com/darknet/yolo/) format
 * Connect your own [Torch Serve](https://pytorch.org/serve/) prediction endpoint and use bounding box predictions as annotation hints

-> **Note for Linux users with Hi-DPI screens**  
-> Currently JavaFX does not follow the system-wide scale settings in some Linux distributions (see e.g. bug reports [here](https://bugs.openjdk.java.net/browse/JDK-8248126) and [here](https://bugs.openjdk.java.net/browse/JDK-8238077)). The easiest way to set the desired scaling manually is by setting the `GDK_SCALE` variable when starting the application from the terminal, for example:
-> ```bash 
-> GDK_SCALE=2x ./boundingboxeditor
-> ```
